f wgzim Patented Aug. 23, 1932 PATENT; OFFICE CARL G. HARRIS, OF ORANGE, MASSACHUSETTS SWIMMING FLOAT Application filed October 9, 1931.

The principal object of this invention is to provide a very simple swimming float consisting of very few parts and especially to eliminate the side rails ordinarily employed and yet be able to have longitudinal side rods for use in handling it and to serve as hand grips.

Other objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawing in which the figure is a perspective view of a float constructed in accordance with this invention.

The float is made up of balsa wood or other self-sustaining wood of a very light and buoyant character. As shown, the float proper is made up of a series of balsa wood boards 10 which may be glued together but are secured by cross rods 11 extending through them so 29 that the float will have the appearance of a single plank of balsa wood. It may be rounded off at the two ends as indicated but the sides are made flat. The rods 11 extend into a pair of slide blocks 12, the rods of course 5 going entirely through the boards of balsa wood and being secured to the blocks 12 in any desired manner.

These blocks are also secured to the boards 10 and the rods 11 by fastening devices 13 in the form of nails, screws or dowels. These blocks are shown as convex on their outer surfaces and each one is provided with a longitudinal groove 15 into which extends the ends of a side rod 14; of wood or other material. The side rod is secured to the blocks by the fastening devices 13 as indicated.

In use this constitutes a very light and buoyant float and can be used as a life pre- A server or in fact as a surf board. The rods 14: serve as handles by which the device can be carried on land and by which it can be thrown into the water, but the pricipal use is to constitute grips by which the swimmers can grasp the float. By this simple expedient a very simple construction is obtained and one containing very few parts which are secured together in such a way as to cost very little for assembly.

The float does not need to be covered with canvas but it can be painted or covered with Serial No. 567,927.

a water-proof composition to prevent the en- 'try of water into the grain of'the wood and between the several boards of which the float is composed.

Although I have illustrated and described other and the side ones constituting the sides of the float, cross rods extending through themrby which they are secured together to form a single plank having a uniform surface, side blocks on the sides of said float near F the ends and secured to the cross rods, and longitudinal rods or grips mounted on the outer surfaces of said side blocks and spaced from the sides of the float.

2. As an article of manufacture, a swimming float or the like consisting of a series of boards of balsa wood in Contact with each other and the side ones constituting the sides of the float, cross rods extending through them by which they are secured together to form a single plank, and longitudinal rods or grips mounted along said side boards, and spaced from the sides of the float.

In testimony whereof I have hereunto affixed my signature.
